DAIRY DEMONSTRATION FARM, DENISON, TEX. 



A dairy demonstration farm located about 3 miles east of Denison, 

 Tex., owned by a company organized by the Denison Chamber of 

 Commerce, is operated under a cooperative arrangement by which 

 the Dairy Division provides a manager and the company pays all 

 other expenses. The object is to show what can be done under 

 ordinary conditions by correct methods of dairy farming. 



From a typical worn-out cotton farm in 1908, stocked with or- 

 dinary native or scrub cattle, the farm and herd have been improved 

 until the soil is very rich. Forage and silage crops are now grown; 

 the herd has been improved by the use of pure-bred Jersey bulls and 

 by record keeping and selection; the average production of butter 

 fat has been practically doubled. The original cows numbered 44. 

 There are now on hand 98 females, including 2 of the original herd, 

 48 milch cows, and 48 heifers. 



MARKET-MILK INVESTIGATIONS. 



The work of the section of market-milk investigations, of which 

 Mr. Ernest Kelly is in charge, is largely educational in character, and 

 is carried on mainly in cooperation with city health departments, 

 with the object of improving local milk conditions. 



CITY MILK SUPPLIES AND MILK IMPROVEMENT. 



In the past year the Dairy Division has lent active aid in improv- 

 ing the milk supplies of 20 cities situated in 11 States. In this 

 work 446 dairy farms and 37 milk plants were scored, nearly four 

 times as many as in the preceding year. Nearly 300 cities are using 

 some form of the score card for dairy farms. 



The Dairy Division has entered into a cooperative agreement with 

 the Office of Markets and Rural Organization to study the handling 

 and delivery of milk in cities, which will be a continuation of work 

 previously carried on by this division. 



Data have been collected on the cost of filling and capping milk 

 bottles. Forms have been devised and published for milk dealers 

 to use in checking up their goods. Every month a circular letter 

 on topics pertinent to milk handling is sent to all milk dealers re- 

 questing it ; the number now receiving this letter is about 600. 



At Cum.berland, Md., three employees of the division spent some 

 time making a thorough survey and introducing efficient inspection. 

 Cooperative work in the IMississippi Valley has been begun with 

 the Bureau of Chemistry, and a party of department experts is trav- 

 eling in that section, doing educational work among the dairymen. 



A study of the relation of bottle caps to the presence of bacteria 

 and to the flavor of milk has been made. A new bacterial rating for 

 scoring milk has been worked out and embodied in a new score card, 

 more uniformly and widely applicable.
